As we already said, Nextoptim “Vrus” is a browser hijacker and as such it would normally try to get added to the user’s browser, whatever that browser might be – Safari, Chrome, Firefox, Opera or some other browsing program. Once it has managed to become a part of the targeted browser, the hijacker would likely attempt to introduce certain changes to it without asking for a permission from the user. We already pointed out what some of those changes could be – the hijacker could try to replace the default search engine of your browser or change its homepage and maybe new-tab page. Also, a new toolbar might get added to the browser. On top of all, you might start getting frequently redirected to web addresses that you never wanted to visit and you might also experience intrusive and obstructive ads generation every time you try to start a new browsing session. All of this can, naturally, drastically decrease the quality of your online experience and it could prevent you from navigating through the Internet without constantly getting disrupted by the annoying activities of the hijacker. Taking all this into account, it should be easy to see why most people would like Nextoptim “Virus” taken away from their machines and luckily for any of you who might be in a similar situation, down below we have posted a guide that contains detailed instructions focused on removing and uninstalling the irritating software piece. Make sure to give it a go in case Nextoptim “Virus” is presently on your machine and if it is making your browsing experience miserable with its constant nagging.
Should you be afraid of hijackers?
Unlike dreaded computer threats like Ransomware, Trojans, Spyware and other similar kinds of malware, hijacker apps are typically not harmful or at least not capable of directly causing damage to your system and to your virtual privacy. Most hijacker apps are, in fact, legal pieces of software and although thy might oftentimes be a little bit too annoying, their main purpose still normally revolves around online promoting and advertising (hence the changes to your browser and the frequent generation of adverts and page redirects). Such activity is normally not directly harmful to your PC. Sure, it might slow-down the machine and your Internet due to an increased use of system resources like CPU, RAM and Internet bandwidth but no real harm should come from that. However, it is advisable that you keep your distance from the ads and the page redirects that might pop-up on your screen as they might not always be coming from the most reliable of sources. Also, we advise you to abstain from using the hijacker-imposed search engine, homepage, new-tab page and toolbar as they might land you on promoted pages some of which might not be reliable. All in all, even though a typical hijacker browser redirect like Nextoptim should not represent a significant security hazards for your system, if you really want to keep your system safe from real malware like Ransomware and Trojan Horse viruses, we advise you to stay away and not with anything that the hijacker puts on your screen.
Ways a browser hijacker/redirect could get installed on your computer
There are numerous techniques used for distributing unwanted software pieces like Nextoptim. There are the infamous spam e-mails, there are also various forms of malvertising and social engineering, different pirated or low-quality program downloads and many other similar methods. However, the one thing that most users seem to fall for is the file bundling. With the use of this methods, the developers of hijacker apps add their products to another program’s installer forming an installation package (a program-bundle). Typically, users tend to go for the Quick installation configuration and in most cases this also allows the added app (in this case the hijacker) to get installed along the main program. To avoid this, you need to opt out of the hijacker’s installation by accessing the Custom setup menu and unchecking the checkboxes next to the optional installs that you deem unwanted. That way, you could still install the program that you want while leaving the pesky hijacker out of your system.
